"Per this thread, I would suggest to anyone that hasn't already to read Tim Gallwey's book, "The Inner Game of Golf." Trying to play different shots and talking on a cell phone while hitting may serve the same purpose: to distract ego-driven, control-freak "Self 1" from getting in the way of intuitive "Self 2."

I'll be sure to tell that to the player I mentioned who was chipping beautifully with either arm while talking on his cell phone but I know him and I'm pretty sure he'll just stare at me in silent disbelief. I will ask him if he was doing it to distract his ego-driven, control-freak Self 1 from getting in the way of his intuitive Self 2 but I have a feeling he might just say he was fooling around chipping and pitching while he had a fairly long conversation with his girl-friend.
